For example, as illustrated in the reference FIGS. 10 and 11 which show the usage state, by using together with a vent cap, decrease in the ventilating function, which is caused by adhesion of dirt from an outside to the present article, can be prevented, and furthermore as illustrated in the reference FIG. 12 which shows the usage state, the ventilating passage as indicated by arrows can be secured.
